IMPROVEMENT IN ANIMAL-SHEARING MACHINES.-

Specification forming part of Letters Patent No. 205,450, dated June 25,1878; application filed April 10, 1878.

To all whom it may concern:

Be it known that we, EDWARD J. \VATSON, of Greenbush, in the'county ofRensselaer and State of New York, and FRANK ARMSTRONG, of Bridgeport, inthe county of Fairfield and State of Connecticut, have invented certainnew and useful Improvements in Animal- Shearing Machines; and we dohereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanyin g drawings, making apart of this speci fication.

Our invention relates to certain new and useful improvements inanimal-shearing devices for which Letters Patent were granted to E. J.Watson, November 27, 1877, No. 197,7 04.

It has for its object to provide a means for regulating the depth ofcut; and consists in combining with the shearing-blades a secondary combor its equivalent, which, While it does not cover the hair of theanimal, holds the cuttingblades any given distance from the hide, andhence produces the results aimed at.

As this invention, as before stated, relates to improvements on theLetters Patent above mentioned, in the drawings we have not illustratedin detail the means for operating the knives, as that is immaterial.

Figure 1 is a side view of a shearing device embracing our improvements,and Fig. 2 is a front or top view of the same.

Similar letters indicate like parts in the two figures.

A is the handle, secured to the lower end of the back plate B, which isprovided at its upper end with the usual fixed cutter O. D is avibrating plate or arm, pivoted at a to the plate B, and operated bysuitable mechanism, through the medium of a crank-arm, E. To the top ofthe vibrating plate D is secured another cutter, F, which lies againstthe cutter O, and when vibrated clips the hair protrudin g through saidcutter. Gr is an ordinary comb, made of hard rubber or other suitablematerial, removably attached to a metal frame, H, which is provided ateach end with cars 11. This frame is secured to the back plate B by thumb-screws c, in such manner that the frame may vibrate upon the same, tocause the comb G to approach or recede from the back plane of the cutterO. I is a set-screw passing through a curved slot, 61, in the plane D,and having its bearing in the back plate B at a point above the pivotalpoints 0 of the combframe, and of such length as to reach the frame H inits extreme positions.

From this construction it will be seen that the comb G may be adjustedto any distance from the back cutter O, and the set-screw I caused torest against the inside of the frame H, so that it cannot by pressure beforced nearer the cutter than desired.

What we claim as new, and desire to secure by Letters Patent, is-

1. In combination with the cutting mechanism of a shearing-machine, ahinged comb adapted to be adjusted at diEerent distances from thecutting mechanism, substantially as and for the purpose set forth.

2. In combination with a shearing device and a secondary adjustable combor its equivalent, and frame H b, the set-screw I, for holding andadjusting the comb, substantially as hereinbefore set forth.

In testimony whereof we have hereunto set our hands and seals this 9thday of April, A.
